The unit aims to introduce mechanics of deformable bodies and some elements of structural analysis. The unit investigates stress and strain, structural actions for a range of typical structures, strength and serviceability concepts, as well as stress distribution in beams. An understanding of column types and failure modes and torsion will be gained.

At the completion of this unit students will be able to:

  1. describe the principles of structural actions, stresses, strains and resultant failures in common structural elements
  2. calculate the resultant stresses and deflections that occur in beams and columns under applied loads
  3. communicate calculations, designs and laboratory test results in a professional manner in written reports
  4. apply this knowledge to the design of simple structural elements utilising design codes
  5. collaborate with other students in small teams to produce design solutions and reports.
  • Invigilated Exam (55%)
  • Mid-study period test (15%)
  • Project — Practical Projects (30%)

Mandatory conditional prerequisites

You must either have successfully completed the following unit(s) before starting this unit, or currently be enrolled in the following unit(s) in a prior study period; or enrol in the following unit(s) to study prior to this unit:

Please note that your enrolment in this unit is conditional on successful completion of these prerequisite unit(s). If you study the prerequisite unit(s) in the study period immediately prior to studying this unit, your result for the prerequisite unit(s) will not be finalised prior to the close of enrolment. In this situation, should you not complete your prerequisite unit(s) successfully you should not continue with your enrolment in this unit. If you are currently enrolled in the prerequisite unit(s) and believe you may not complete these all successfully, it is your responsibility to reschedule your study of this unit to give you time to re-attempt the prerequisite unit(s).
